Check P0051 Fault Code

When you check engine light came on code P0051 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the P0051 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P0051 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.

P0051 Possible Fix :

Detonation, or spark knock, is a type of combustion caused by the buildup of too much heat and pressure in the engine's combustion chamber. When this happens, you should be able to hear a metallic knocking or pinging noise. A small amount of detonation usually won't cause major damage, but heavy knocks or prolonged detonation can cause serious damage to your parts. It can punch holes in your pistons, crush rod bearings, blow head gaskets, crack rings, and pound out piston ring grooves. Prolonged pinging noises are a definite cause for concern.

P0051 OBD-II Diagnostic Powertrain (P) Trouble Code Description P0051 OBD-II Trouble Code Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches t Reason For P0051 Code The reason of P0051 OBD-II Fault Code Check is P0051 HO2S Heater Control Circuit Low Bank 2 Sensor 1.

P0051 Solution:

Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

How to Clear P0051 Trouble Code

An OBD 2 scanner is the best and safest way to erase a DTC from your car's system. This scanner communicates with the car's computer and instructs the computer to erase the code. It does not change or tweak the settings from inside the car or its systems.
